INSTALLATION MANUAL -PHOTOVOLTAIC MODULES-
1. INSTALLATION
The mounting method has been verified by SHARP and NOT
CERTIFIED by a third party organization. Please review the
descriptions and drawings carefully; not mounting the modules
according to one of these methods may void your guaranty.
Mounting Using Clips: Clamping on Longer Frame (Figure2)
The modules can be mounted using clips (clamps) designed for solar
modules as defined in the following Figures. Note that the mounting clips
should meet the required dimensions as defined in the Figure1. Note that
the CLIP CENTER POSITION (e) is important as specified in the Figure2.
The module must be supported on the array system and should overlap
the array rail by at least 10mm. The array rails (see pointillist image, row
or vertical row) must support the bottom of the frames and must be
continuous piece (no breaks in the rail).
2. ELECTRICAL INSTALLATION INSTRUCTION
CABLE requirement
Conductor size: 4.0mm
2
Min.
Cable type: XLPE cable (H1Z2Z2-K cable)
Maximum DC voltage: 1.5kV
Rating temperature: -40°C to +90°C,
Module configuration (Recommend)
# Maximum series configuration: please refer to Table-1
(This value is calculated under the condition of Voc at -40 °C.)
# Maximum parallel configuration:
# Maximum parallel configuration: (Parallel connection of each
string shall be conducted with following two options. Any other
parallel connections are prohibited.)
a) Case of using the diodes; 1 diode per maximum 2 parallel
strings (Connect a diode or more in series for every string or
every 2 parallel strings for protection of module from reverse
current over load.)
b) Case of using the fuses; 1 fuse per every string (Connect a
fuse for every single string for protection of module from
reverse current over load.)
CONNECTOR requirement
The module shall be mated to the same connectors;
Type (Brand):
PV-SY02 (Zhejiang Twinsel Elecronic Technology Co., Ltd.)
3. WARNING
Keep all MODULES and electriacal
CONNECTORS clean & dry before
installation.
4. Disposal
Dispose photovoltaic modules
properly. For Information about the
proper disposal, contact your local
recycling site.

Under normal conditions, a photovoltaic module is likely to experience conditions that produce more current and/or voltage than
reported at Standard Test Conditions. Accordingly, the values of Isc and Voc marked on this module should be multiplied by a
factor of 1.25 when determining component voltage ratings, conductor capacities, fuse sizes and size of controls connected to the
module output.
Class for protection against electric shock
This module is classified as ‘’ClassⅡ’’ according to IEC61730.
This module is intended for installation where general user
access and contact to insulated live parts is anticipated.
FIRE RATING
This module is rated as “Fire safety class C” according to UL790.
